I for one am exited about this as I value the 24-28 range slightly higher than the 70-100 range.

I'm relieved with the specifications. There will be no temptation whatsoever to buy this one. I find the 100 mm zoom range and the F stop at max zoom the most limiting factor, and 28 mm at the wide end just fine. Bringing the lens down to 24 mm is going to mean major barrel distortion that is going to have to be corrected in the RAW software. The correction required for the existing 28 mm is near the maximum that can be corrected already.
